I have a 10" slow speed electric orbital buffer I use on my car, but I bought a 6" for use on the VX since the body panels don't have as much overall area. They aren't the fanciest, or latest and greatest, but I've found that the compounds and pads are where your money is best spent. For clearcoat finishes, sponge pads and a good clearcoat polish will give paint that "always wet" look. The clearcoat polish I use is the type used by professional body shops, so you have to get it at something like an autobody supply store, but it shouldn't run more than $20/quart. #051131-05993 is the actual 3M part# I've used with success. It's safe for use by hand or machine.
